Abstract

Deformation of lucerne root hairs caused by the action of beta-indolylacetic acid (IAA) and alpha-naphthylacetic acid (NAA) differs from deformation induced by Rhizobium meliloti. High concentrations of IAA brought about abnormal deformation of root hairs wherease the action of average concentrations of IAA resulted in corkscrew-like winding and wavy structures. No deformation was observed under the action of low IAA concentrations or the cultural broth of Rhizobium. Infective filaments in root hairs were found only upon infection with pure cultures of Rhizobium.

摘要

β-吲哚乙酸（IAA）和α-萘乙酸（NAA）作用引起的苜蓿根毛变形不同于苜蓿根瘤菌诱导的变形。高浓度的IAA导致根毛异常变形，而平均浓度的IAA作用则导致根毛呈螺旋状缠绕和波浪状结构。在低浓度IAA或根瘤菌培养液作用下未观察到变形。只有在接种根瘤菌纯培养物后才在根毛中发现感染丝。
